Genetics of Behavior: Fire Ants

ResearchBlogging.orgA common presumption is that behavior is part of phenotype, and since phenotype arises from genotype (plus/minus Reaction Norm), that there can be a study of “behavioral genetics.” This is certainly an overstatement (or oversimplification) for organisms with extensive and/or complex neural systems, such as humans and mice. Neural systems probably evolved (not initially, but eventually) to disassociate behavior with the kind of pre-determined micro-management of behavior that a simple gene-behavior link requires. However, in organisms with neural systems the size of the period at the end of this sentence, we often do see cases of allelic variations causing behavioral variation in the whole organism. The study discussed here is an example of this. Continue reading Genetics of Behavior: Fire Ants

The Boomerang Experiment Worked

… and, gave positive results. I know you have been waiting in anticipation for the results of an experiment in which an astronaut was going to toss a boomerang in space to see if it came back.Well, it worked:

Boomerang works in space: Japanese astronaut from PhysOrg.com
In an unprecedented experiment, a Japanese astronaut has thrown a boomerang in space and confirmed it flies back much like on Earth.[]

Whew, this one had me really worried…

MS Down, Mac, Linux Up

For the first time in ages, the sale of new PCs with Windows as a percentage of the PC market is declining sharply. The new winner is the Mac, but, while no one does a good job of tracking the still-new, pre-installed Linux desktop market, it’s also clear that Linux is finally making impressive inroads into Windows’ once unchallenged market share.


Myers and Dawkins Speak Out on Expelled Expulsion

This little video, very nicely done, should be shown in all social studies classes in America, discussed at length, and it should be on the exam. From now on.Source: Richarddawkins.netLord Privy Seals All The Way Down … arf arf.See also:PZ Myers Expelled, Gains SainthoodExpelled!

UPDATE on Expelled-Gate

More links have been added to the ever growing sampling of commentary on the Myers-Dawkins Expelled-Gate Event.As e we move ever closer to the self destruction of the Intelligent Design Movement, I note that the Expelled Gate Even now is now competing for space in the Wikipedia Entry on Irony (but some help may be needed … there seems to be some creationists there erasing themselves whenever the evolutionists add them in).
